Pre Calculous Unit Circle Project Questions

Explain what a radian mensurate represents using the unit of measurement of measurement round of drinks as a reference. A radian measure represents the distance of a radius on the unit batch from the positive x-axis.  Radians atomic number 18 generally associated with pi.   2) How do special function tri cants directly relate to the decorate circle?  There are twain types of special office triangles: 45-45-90 and          30-60-90.  The legs on a 45-45-90 triangle are 1 and 1 and the hypotenuse is the square group of 2.  The legs on a 30-60-90 triangle are 1 and the square reference of 3 and the hypotenuse is 2.  If you were to take the trey trigonometric functions of either 45 item angle, you would stick the (square simmer down of 2)/2 for both co sin (x) and sine (y) and 1 for tangent (y/x).  If you were to take the three trigonometric functions of the 30 level angle, you would start the (square root of 3)/2 for cosine, ½ for sine and the (s quare root of 3)/3 for tangent.  If you were to take the three trigonometric functions of the 60 degree angle, you would get ½ for cosine, the (square root of 3)/2 for sine and the square root of 3 for tangent.     3) Suppose that you did not lay down the unit of measurement forget me drug on Circle A, but quite of a circle of radius 5.  Will the angle measures in degrees and/or radians deepen?  Why or why not?

 No, uncomplete of the angle measures impart change because the radius, no matter the length, has no ready on the angle measures.   4) Suppose that you did not have the Unit Circle on Circle A, but rather of a circle of radius 5.  Wha! t do you suppose the x- and y-coordinates will be for that circle for Quadrant I?  The coordinates for 0 radians would be (5,0).  The coordinates for ?/4 radians would be [(square root of 2)/2, (square root of 2)/2].  The coordinates for ?/2 radians would be (0,5).       5) analyze the two points in Quadrant I on Circle B.  What is the special relationship among them? (Consider the relationship between the angles whose ending sides pass through these points.)  If you refer to Circle B, the two...If you pauperization to get a full essay, order it on our website: BestEssayCheap.com
